XML to JSON API Proxy for Quick Mash-Ups

XML to JSON API Proxy for Quick Mash-Ups

While building our company dashboard, which was mentioned in our previous blog post on SVG with Raphael, I came across a problem with the project management tool we use – Pivotal Tracker.

The Pivotal Tracker API is only in XML, which means you can’t do cross-domain requests and access the API via javascript. This meant that if I wanted to extract data about the status of our user stories, I would have to do it on the server side. As everything so far had been done with javascript on the client side, I was reluctant to start making things more complicated.

I contacted Pivotal, who said they might think about adding JSON at some point, but I didn’t want to wait for them to sort it out. Instead, I built a quick API proxy that allows you to make a request to a XML API and get back JSON. So, now, I can do this in my javascript:

$.ajax({ type: "GET", url: 'https://xml2json.heroku.com', data:'url=https://www.pivotaltracker.com/services/v3/projects/'+projectId+'/iterations/current?token='+trackerToken, dataType: 'jsonp', success: function(data) { console.log(data); } });

It will proxy the GET request to the API and convert the XML response into JSON, via https://xml2json.heroku.com (supports JSONP). I’ve put the code on GitHub https://github.com/bitzesty/xml2jsonp in case anyone else needs to do the same thing.
